Terminology is O — output, I — input, Up — weak pullup enabled, Down — weak pulldown enabled, Low — output driven
low, High — output driven high. A dash on the left side of the slash denotes that both the input and output buffers for the
pin are off. A dash on the right side of the slash denotes that there is no weak pull up/down enabled on the pin. The signal
name to the left or right of the slash indicates the pin is enabled.

Function after reset of GPI is general-purpose input. A dash on the left side of the slash denotes that both the input and
output buffers for the pin are off. A dash on the right side of the slash denotes that there is no weak pull up/down enabled
on the pin.
